ok first they are from seed, idk wut kind of seed, probably shitty kind, but im useing the curly bulbs, the ones that save energy, two of them, 1700 lumens each, n there about an inch to an two inches away from the plants, im using just regular potting soil, and i water them in the morining a little, just enough to wet the soil, and at night the same, i have two computer fans blowing air around, one blowing fresh air in, n the other just to cerculate, and a Co2 chamber(2 liter bottle, with yeast n sugar mix, i have about 9 little plants, and im going to narrow them down as soon as i find out which ones are male n female, but i just want to know why my plant is getting brown, also this plant that is brown is different from the others, instead if being kind of shiny its more like dried out looking and dull, idk if that makes a difference, oh and its also the biggest one so far
